Topic: The Structure of Joints

I need to know more about the Structure of the Joints, like the big and little thing if it could be 250 words that would be even better.

Answer 1

Joints are the place where two bones come together and meet. This allows the bones to move. There are three main types of joints i.e Fibrous joint which are immovable in nature, Cartilaginous joint which are partially moveable and the Synovial joint which are freely moveable joint. There are three types of fibrous joints i.e sutures, gomphoses and syndesmoses joints. There are two types of cartilaginous joints i.e synchondroses and symphyses. There are six types of synovial joints i.e Ball and socket joints, saddle joints, planar joints, hinge joints, condyloid joints and pivot joints. The joints have many structures such as cartilage, ligaments, synovial membrane, synovial fluid, ligaments, tendons, meniscus and bursas. Cartilage are tissues which covers surfaces of bones at the joints and they play a role in reducing the friction between the bones during movement. Synovial membrane are the tissues which forms the lining at the joint and forms a capsule. Synovial membrane secretes a clear fliud called synovial fluid which helps in lubricating the joint. Ligaments are tough and elastic connective tissue which gives support to the joint and controls the joint movements. Tendons are connective tissues which joins muscles to bones and controls the movement of bones at joints. Meniscus are the curved portion of cartilage found in some joints. Bursas are fluid filled sacs which are present between bones or ligaments. Bursas helps in cushioning the joints against frictions.
